    Oracle问题之ORA-12560TNS:协议适配器错误

    一、造成ORA-12560: TNS: 协议适配器错误的问题的原因有三个

    1.监听服务没有起起来。windows平台个一如下操作:开始---程序---管理工具---服务,打开服务面板,

      启动OracleOraDb11g_home1TNSlistener服务。
      
      

    2.database instance没有起起来。windows平台如下操作:开始---程序---管理工具---服务,打开服务

      面板,启动OracleServiceBOOKSALES, BOOKSALES就是你的database SID    
      

     3.注册表问题。regedit,然后进入HKEY_LOCAL_MACHINESOFTWAREORACLEHOME

      将该环境变量ORACLE_SI
    D设置为XXXX, XXXX就是你的database SID.
      
      

      

      

      

      或者右击我的电脑,属性--高级--环境变量---系统变量--新建
    ,变量名=oracle_sid,变量值=XXXX, XXXX就是你的database SID.

      或者进入sqlplus前,在command line下
    输 set oracle_sid=XXXX, XXXX就是你的database SID.

      经过以上步骤,一般就可以解决问题。

    二、如果还没有解决的话则会遇到以下问题:

    1、执行请求的操作时遇到错误:

    
    

    IO 错误: The Network Adapter could not establish the connection

    
    

    供应商代码 17002

    
    

    2、执行请求的操作时遇到错误:

    
    

    Listener refused the connection with the following error:
    ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

    
    

    供应商代码 12514


    三、解决方法如下:

      假如只有一个数据库的话:

      1、找到如下路径:

        D:installoracleoracle-installproduct11.2.0dbhome_1NETWORKADMIN

        



      2、将文件中的内容修改如下,当然要结合自己的实际情况做简单修改:
         //listener.ora
     1 # listener.ora Network Configuration File: D:installoracleoracle-installproduct11.2.0dbhome_1
    etworkadminlistener.ora
     2 # Generated by Oracle configuration tools.
     3 
     4 SID_LIST_LISTENER =
     5   (SID_LIST =
     6     (SID_DESC =
     7       (SID_NAME = CLRExtProc)
     8       (ORACLE_HOME = D:installoracleoracle-installproduct11.2.0dbhome_1)
     9       (PROGRAM = extproc)
    10       (ENVS = "EXTPROC_DLLS=ONLY:D:installoracleoracle-installproduct11.2.0dbhome_1inoraclr11.dll")
    11     )
    12     (SID_DESC =
    13       (SID_NAME = BOOKSALES)
    14       (ORACLE_HOME = D:installoracleoracle-installproduct11.2.0dbhome_1)
    15    (GLOBAL_DBNAME = BOOKSALES)
    16  )
    17   )
    18 
    19 LISTENER =
    20   (DESCRIPTION_LIST =
    21     (DESCRIPTION =
    22       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    23     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    24     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    25     (ADDRESS = (PROTOCOL = TCP)(HOST = acer)(PORT = 1521))
    26     )
    27   )
    28 
    29 ADR_BASE_LISTENER = D:installoracleoracle-install
    View Code

         //sqlnet.ora    

     1 # sqlnet.ora Network Configuration File: D:installoracleoracle-installproduct11.2.0dbhome_1
    etworkadminsqlnet.ora
     2 # Generated by Oracle configuration tools.
     3 
     4 # This file is actually generated by netca. But if customers choose to 
     5 # install "Software Only", this file wont exist and without the native 
     6 # authentication, they will not be able to connect to the database on NT.
     7 
     8 SQLNET.AUTHENTICATION_SERVICES= (NTS)
     9 
    10 NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
    View Code

         //tnsnames.ora

     1 # tnsnames.ora Network Configuration File: D:installoracleoracle-installproduct11.2.0dbhome_1
    etworkadmin	nsnames.ora
     2 # Generated by Oracle configuration tools.
     3 
     4 BOOKSALES =
     5   (DESCRIPTION =
     6     (ADDRESS_LIST =
     7       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
     8     )
     9     (CONNECT_DATA =
    10       (SERVICE_NAME = BOOKSALES)
    11     )
    12   )
    View Code
    
    

       3、重新启动 tnslistener

       4、测试的时候要注意修改对应数据库的用户名和密码

        Oracle SQL Developer连接的时候也要注意用对应的用户名和密码

        

        

        

    执行请求的操作时遇到错误:

    IO 错误: The Network Adapter could not establish the connection

    供应商代码 17002

    执行请求的操作时遇到错误:

    Listener refused the connection with the following error:
    ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

    供应商代码 12514

     

    也是按照上面修改配置文件
